Just think of the wattage involved. It would destroy your batteries amp hour capacity.
As for towing, I doubt if the tanks were warm to start out, that they would freeze in route.
I worried about the plumbing since we drive to FLA from PA in January.
Last year it was VERY cold and we did not get above freezing until GA.
I thought about leaving the heater running with the cabinets open, but decided against it for safety reasons.
As it turned out we had planned our trip with 4 hour legs between campgrounds and the camper stayed well above freezing the entire trip with no additional heat. I did leave the cabinets to the plumbing open so the warmer air in the camper would circulate into the pipes.
I also used a 12DC clip on fan to force the warm air into the cabinets while we traveled.
